      stm32mp1: SCMI clock and reset service in SP_MIN · fdaaaeb4
      Etienne Carriere authored
      
      
      This change implements platform services for stm32mp1 to expose clock
      and reset controllers over SCMI clock and reset domain protocols
      in sp_min firmware.
      
      Requests execution use a fastcall SMC context using a SiP function ID.
      The setup allows the create SCMI channels by assigning a specific
      SiP SMC function ID for each channel/agent identifier defined. In this
      change, stm32mp1 exposes a single channel and hence expects single
      agent at a time.
      
      The input payload in copied in secure memory before the message
      in passed through the SCMI server drivers. BL32/sp_min is invoked
      for a single SCMI message processing and always returns with a
      synchronous response message passed back to the caller agent.
      
      This change fixes and updates STM32_COMMON_SIP_NUM_CALLS that was
      previously wrongly set 4 whereas only 1 SiP SMC function ID was to
      be counted. STM32_COMMON_SIP_NUM_CALLS is now set to 3 since the
      2 added SiP SMC function IDs for SCMI services.

      Enable -Wredundant-decls warning check · ca661a00
      Madhukar Pappireddy authored
      
      
      This flag warns if anything is declared more than once in the same
      scope, even in cases where multiple declaration is valid and changes
      nothing.
      
      Consequently, this patch also fixes the issues reported by this
      flag. Consider the following two lines of code from two different source
      files(bl_common.h and bl31_plat_setup.c):
      
      IMPORT_SYM(uintptr_t, __RO_START__, BL_CODE_BASE);
      IMPORT_SYM(unsigned long, __RO_START__, BL2_RO_BASE);
      
      The IMPORT_SYM macro which actually imports a linker symbol as a C expression.
      The macro defines the __RO_START__ as an extern variable twice, one for each
      instance. __RO_START__ symbol is defined by the linker script to mark the start
      of the Read-Only area of the memory map.
      
      Essentially, the platform code redefines the linker symbol with a different
      (relevant) name rather than using the standard symbol. A simple solution to
      fix this issue in the platform code for redundant declarations warning is
      to remove the second IMPORT_SYM and replace it with following assignment
      
      static const unsigned long BL2_RO_BASE = BL_CODE_BASE;

      stm32mp1: add authentication support for stm32image · 4bdb1a7a
      Lionel Debieve authored
      
      
      This commit adds authentication binary support for STM32MP1.
      It prints the bootrom authentication result if signed
      image is used and authenticates the next loaded STM32 images.
      It also enables the dynamic translation table support
      (PLAT_XLAT_TABLES_DYNAMIC) to use bootrom services.

      stm32mp1: add general SYSCFG management · f33b2433
      Yann Gautier authored
      
      
      The system configuration controller is mainly used to manage
      the compensation cell and other IOs and system related settings.
      
      The SYSCFG driver is in charge of configuring masters on the interconnect,
      IO compensation, low voltage boards, or pull-ups for boot pins.
      All other configurations should be handled in Linux drivers requiring it.
      
      Device tree files are also updated to manage vdd-supply regulator.

      stm32mp1: add OP-TEE support · 1989a19c
      Yann Gautier authored
      
      
      Support booting OP-TEE as BL32 boot stage and secure runtime
      service.
      
      OP-TEE executes in internal RAM and uses a secure DDR area to store
      the pager pagestore. Memory mapping and TZC are configured accordingly
      prior OP-TEE boot. OP-TEE image is expected in OP-TEE v2 format where
      a header file describes the effective boot images. This change
      post processes header file content to get OP-TEE load addresses
      and set OP-TEE boot arguments.

      Sanitise includes across codebase · 09d40e0e
      Antonio Nino Diaz authored
      Enforce full include path for includes. Deprecate old paths.
      
      The following folders inside include/lib have been left unchanged:
      
      - include/lib/cpus/${ARCH}
      - include/lib/el3_runtime/${ARCH}
      
      The reason for this change is that having a global namespace for
      includes isn't a good idea. It defeats one of the advantages of having
      folders and it introduces problems that are sometimes subtle (because
      you may not know the header you are actually including if there are two
      of them).
      
      For example, this patch had to be created because two headers were
      called the same way: e0ea0928 ("Fix gpio includes of mt8173 platform
      to avoid collision."). More recently, this patch has had similar
      problems: 46f9b2c3 ("drivers: add tzc380 support").
      
      This problem was introduced in commit 4ecca339
      
       ("Move include and
      source files to logical locations"). At that time, there weren't too
      many headers so it wasn't a real issue. However, time has shown that
      this creates problems.
      
      Platforms that want to preserve the way they include headers may add the
      removed paths to PLAT_INCLUDES, but this is discouraged.

      Standardise header guards across codebase · c3cf06f1
      Antonio Nino Diaz authored
      
      
      All identifiers, regardless of use, that start with two underscores are
      reserved. This means they can't be used in header guards.
      
      The style that this project is now to use the full name of the file in
      capital letters followed by 'H'. For example, for a file called
      "uart_example.h", the header guard is UART_EXAMPLE_H.
      
      The exceptions are files that are imported from other projects:
      
      - CryptoCell driver
      - dt-bindings folders
      - zlib headers
